When the eccentric motor 21 moves, the eccentric output shaft 211 rotates about the central axis of the eccentric motor 21 to have a motion component parallel to the axis of the plunger 221 and a motion component parallel to the length direction of the elongated hole 2221. Because the eccentric output shaft 211 extends into the elongated hole 2221, the eccentric output shaft 211 can move along the length direction of the elongated hole 2221 relative to the elongated hole 2221, that is, the elongated hole 2221 and the eccentric output shaft 211 are cooperatively arranged, so that the movement of the movable rod 222 along the length direction parallel to the elongated hole 2221 can be eliminated, and the eccentric motor 21 can only drive the movable rod 222 to move along the direction parallel to the central axis of the movable rod 222, that is, the movable rod 222 reciprocates along the cavity wall of the pumping cavity 1181 in the pumping cavity 1181.

Because the upper port of the pump liquid cavity is communicated with the liquid suction groove 115 through the sealed cavity, when the driving unit drives the movable rod 222 to move in the pumping column cavity 1181 along the direction far away from the sealed cavity, the volume of the pump liquid cavity is increased, the air pressure in the sealed cavity is reduced, and detergent enters the liquid suction groove 115 from the detergent cavity 121 through the liquid suction cavity 1161 under the negative pressure action of the sealed cavity and flows into the liquid discharge cavity 1171 from the liquid suction groove 115; when the driving unit drives the movable rod 222 to move in the pumping column cavity 1181 in the direction close to the sealed cavity, the volume of the pumping liquid cavity is reduced, the air pressure in the sealed cavity is increased, and because the one-way valve is arranged in the liquid absorbing cavity 1161, the detergent cannot flow back to the detergent cavity 121 through the liquid absorbing cavity 1161, and only can flow into the temporary storage cavity 122 through the liquid discharging cavity 1171, so that the detergent is further prevented from remaining in the liquid absorbing groove 115. That is, the volume and pressure of the pump liquid cavity generated by the movement of the movable rod 222 in the pumping column cavity 1181 can drive the detergent to enter the temporary storage cavity 122 from the detergent cavity 121 through the liquid absorption cavity 1161, the liquid absorption groove 115 and the liquid discharge cavity 1171, and further enter the input port 123 from the temporary storage cavity 122.

Preferably, in the present embodiment, the movable lever 222 has a plate-shaped structure, and is perpendicular to the eccentric output shaft 211. First guide grooves 1182 are formed in positions, corresponding to two sides of the movable rod 222, of the inner cavity wall of the pumping column cavity 1181, and the first guide grooves 1182 are arranged along the length direction of the pumping column cavity 1181. The two sides of the movable rod 222 respectively extend into the corresponding first guide grooves 1182 to be slidably connected with the first guide grooves 1182, so that the guiding effect on the movement of the movable rod 222 is improved, and unnecessary rotation of the movable rod 222 in the reciprocating process is avoided.

Further, a guide post 223 is disposed on a side of the movable rod 222 away from the eccentric motor 21, a second guide groove 1183 is disposed on an inner cavity wall of the pumping post cavity 1181 corresponding to the guide post 223, and an end of the guide post 223 extends into the second guide groove 1183 and is slidably connected with the second guide groove 1183. The arrangement of the guide column 223 and the second guide groove 1183 can further provide a guide effect for the movement of the movable rod 222, and improve the reliability and stability of the movement of the movable rod 222.

In this embodiment, the plunger 221 and the pumping column cavity 1181 are both cylindrical structures, which facilitates the processing and setting and reduces the resistance to the reciprocating motion. In other embodiments, plunger 221 and pumping column cavity 1181 may also have other structural forms such as an oval shape and a rectangular shape, as long as the shapes of plunger 221 and pumping column cavity 1181 are matched, and plunger 221 is capable of sliding in pumping column cavity 1181 and plunger 221 is in sliding seal with pumping column cavity 1181. In this embodiment, the plunger 221 is made of a rubber material, which facilitates sealing between the plunger 221 and the pumping column cavity 1181 during movement of the plunger 221.

In this embodiment, an avoiding port for the movement of the eccentric output shaft 211 is provided at one end of the pumping column cavity 1181 away from the sealed cavity, corresponding to the eccentric motor 21, so as to avoid interference between the pumping column cavity 1181 and the movement of the eccentric output shaft 211.

In this embodiment, the lower case 12 is provided with a mounting post 125, the mounting post 125 has a mounting cavity 1251 with an opening at one end, and the pump connecting post 118 extends into the mounting cavity 1251, so as to further fix the movable rod 222 and the pump connecting post 118. The side of the mounting column 125 far away from the upper box 11 is provided with a pressure regulating hole 126, and the pressure regulating hole 126 is communicated with the pumping column cavity 1181 and is used for regulating the pressure of the side of the pumping column cavity 1181 far away from the sealed cavity, so that the movable rod 222 smoothly slides back and forth in the pumping column cavity 1181.

In the present embodiment, the eccentric motor 21 is connected to the outside of the detergent box 1, and the connection between the eccentric motor 21 and the detergent box 1 is preferably a detachable connection manner such as a threaded connection or a snap connection. An access hole for the eccentric output shaft 211 to extend into the lower box body 12 is formed in the lower box body 12, and the eccentric output shaft 211 penetrates through the access hole to be connected with the movable rod 222.
